Sega Mega-Play

Sega Mega-Play is an arcade system developed by Sega. It is based on Mega Drive/Genesis hardware, and more or less identical.[1] The Mega-Play is JAMMA, and allows 4 cartridges to be plugged in at once.

Megaplay games are specially designed Genesis games, produced for arcade use.

The code of these games has significant modifications when compared to the Genesis releases and in many cases the games are cut-down versions of the games that were released for the home system. For example, Sonic has less zones, and no special stages, thus making it impossible to get all the chaos emeralds. Zones also have a strict timer.

Coins buy you credits on Megaplay games, meaning if you lose all your lives the game is over, like a regular Arcade game.

Like the Megatech the Megaplay boards have an additional Z80 and SMS VDP chip when compared to the standard Genesis hardware. In this case the additional hardware creates a layer which is displayed as an overlay to the game screen. This layer contains basic text such as Insert Coin, and the Megaplay Logo / Instructions during the attract loop.[2]
